When working in X everything behaves normal, including 3D acceleration and vga
clone view.

The system doesn't freeze either, i can startup X again or restart the
system by typing the necessary commands without seeing anything.
When switching between console and X, it also currupts the console view, but the X environment keeps displaying the right thing.

Is this just a bug in the drivers or rather my fault (configuration, ...)? (XFree86log as attachment)
